JOHN B. cruise, on soUTH ATTLEBORO, MASSACHUSETTS, ASSIGNOR TO NEW ENGLAND BUTT COMPANY, or PROVIDENCE, RHODE ISLAND, A CORPORATION or RHODE ISLAND.

Application filed March 9, 1911.

To all whom it may concern:

Be it known that I, JOHN B. CHACE, a

citizen of the United States, residing at A further object of the invention is to provide means for so limiting the upward weight has cleared the ratchet-teeth movement of thetop-weight that such upward movement will be arrested as soon as, or shortly after, the pawl carried by the topa on the bobbin or spool. l

To this end the invention consists primarily in providing a member carried by the top-weight which is adapted to engage a projection or stop on the standard so as to thereby limit the upward movement of the top-weight.

The invention consists in providing a member movably connected to the top weight, which member Will in itsnormal position be in line with the projectionor stop on the standard, but which may be moved out of line with said stop to permit the re moval of the top-weight from the standard.

The invention further consists in the con struction and combination of parts hereinafter described and claimed.

In the drawings: Figure 1 is a view in perspective showing the invention applied in position. Fig. 2 is a fragmentary side elevation of Fig. 1. Fig. 3 is a top plan view, and Fig. 4 is a view in perspective showing the top weight with the present invention attached thereto, in detached position.

In the drawings, the bobbin or spool is designated 1 and is formed at its top with the usual ratchet teeth 2. The bobbin or spool is received on the spindle 3 which latter forms a part of the carrier frame, the latter also including a vertical standard 4.

5 designates the bottom or lower weight which is formed with the usual notch 6 at Specification of Letters Patent.

its base to receive the thread 7 ,-the latter passing through an aperture 8 in standard 4 and from the notch or indentation in the lower weight extends upwardly and is passed through the eye 9 carried by the top end of standard 4. The top weight or spool latch is comprised of a guide part 10 which 15 removable with respect to the standard 4 and receives the latter. An arm member 11 which acts as a pawl for the ratchet teeth 2 is formed integral with the guide 10 and projects outwardly from the front face of the latter at the top thereof, so that the upper side edge of the arm 11 will project above the top end of the guide 10 as illustrated in the drawings. The lock or latch 12 has its rear end pivoted as at 13, to the arm 11 and has its front end 14 of U-shape,

so as to embrace the reduced upper end 15 of the standard 4, as depicted in Fig. 1. On the rear face of the eye 9 a stop 16 is formed, the function of which is to engage with the top face of the U-shaped end 14 of the latch 12 and prevent the top weight from tipping forward, which obviously results in stalling of the spool and consequent breaking of the thread. v

In operation it will be understood that when tension is. exerted on thread 7, the bottom weight 5 will be lifted and the latter coming in contact with the bottom of guide 10, will lift the latter to raise the pawl 11, permitting the bobbin to be rotated. The upward movement of the topmember is restricted by virtue of the U-shaped end 14 of the latch thereof coming in contact with the stop 16, thus positively preventing any tipping forward of the top weight such as will permit the same to assume abnormal rela tion to the standard 4. To remove the top weight to permit a new bobbin to be placed in position it is merely necessary to move the latch 12 about its pivotal point until its end 14 is out of alinement with the stop 16, whereupon the top weight can be removed by a mere lifting movement thereof. It will thus be seen that it is impossible to move the top weight from abnormal position without manually swinging the latch 12 to the position shown in Fig. 4; and thus any tipping forward or other abnormal movement of the latch 10 is prevented in the operation of the machine.

In Fig. 2 the latch is shown in the position in which it engages the stop 16 when f the pawl 11 is in uppermost position, permitting rotation of the bobbin.

It will also be seen that the engagement of the latch or pivoted member 12 with the stop on the standard also serves to prevent the top-weight from being thrown off of the standard, as not infrequently happens with u the usual construction of top-weight when ed member may be made long enough to underlie the boss or projection at the upper end of the standard in which the eye 9 is formed, and in such case this boss .or projection may constitute the stop with which the pivoted member engages to limit the up ward movement of the top-weight.

Having thus described my invention, I claim as new and desire to secure by Letters Patent pp r 1. A thread-carrier having in combination a standard provided with a stop, a, top weight adapted to slide on said standard and provided with a pawl, and a member movably connected to said top-weight and adapted to move into and out of engagement with said stop, said movable member being adapted to be moved out of line with said sto 2 A-thread-carrier having in combination a standard provided with a stop, a top- Weight adapted to slide on said standard and provided with a pawl, and a member pivoted to said top-weightand adapted to move into and out of engagement with said stop, said pivoted member being adapted to g be turned out of line with said stop.

'3. A thread-carrier having in combination' a standard provided with a stop, a topweight adapted to slide on said standard, and provided with a pawl, and amember pivoted to said top-weight and adapted to engage said stop, said pivotedmember being formed with a U-shaped end to embrace said standard. P

a. In a thread-carrier, in combination with a standard having a reduced portion, atop-wei'ghtsliding.on the standard, and a stop carried by the standard above said reduced portion, a latch pivoted to the weight and having a U-shaped free end for engagement with the reduced portion'of' the standard and with said stop, said latch when swung outwardly to become out of alinement with the stop permitting removal of the weight from the standard.

5. In a thread-carrier, in combination with a standard having a reduced portion,

a to a-weight sliding on the standard, a pawl rigi with the weight, astop carried by the standard abovethe reduced portion thereof, and a latch pivoted at one end to the pawl and at its'opposite end being formed with a U-shaped part to recelve the reduced portion of the standard. V V a In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
